川西北地区金成矿的构造—岩浆控制

Structure—magma control of gold mineralization in northwest sichuan

对川西北地区金成矿 ,前人曾过多重视构造—岩相及沉积体系的控矿作用 ,而对构造—岩浆活动的控矿作用关注不够。该文从研究区构造—岩浆活动与金成矿演化 ,构造—岩浆带展布与金矿床 (点 )分布 ,构造—岩浆异常结构对金矿床 (点 )空间定位的制约等方面探讨了本区金成矿的构造—岩浆控制。指出本区构造—岩浆活动与金成矿具有密切的内在成生联系和时空配置关系 ,并显示多样式、多层次的空间结构特征和对应耦合关系 。

The previous geologists once paid much attention to the strata bound process of the structure lithofacies and sedimentary system in the research into the gold mineralization in the northwest sichuan province.However,they paid very little to the strata bound process of the structure magmatic activity.The present paper deals with the structure magma control of the gold mineralization in this region in terms of the relationship between the structure magmatic activrty and the gold mineralization evolution,the relationship between the distribution of the structure magmatic belt and that of the gold deposits(prospeets),and the restraining effect of the structure magmatic anomaly strueture on the spatial location of the gold deposits (prospeets).The research shows that the close association and the temporal and spatial matching are present between the structure magmatic activity in this region and the gold mineralization.In addition,the multi pattern and multi layer spatial structural features and the corresponding coupling relationship displayed in this research are defined as important ore forming geological anomaly controlling the formation and distribution of the gold deposits in this region.
